# Security Testing and Calibration
|
|
|
|
This project includes fuzz tests and a calibration routine to tune Argon2 parameters for your hardware.
|
|
|
|
## Running Fuzz Tests
|
|
|
|
The fuzz tests exercise encryption and decryption with random data using [Hypothesis](https://hypothesis.readthedocs.io/).
|
|
Activate the project's virtual environment and run:
|
|
|
|
```bash
|
|
pytest src/tests/test_encryption_fuzz.py
|
|
```
|
|
|
|
Running the entire test suite will also execute these fuzz tests.
|
|
|
|
## Calibrating Argon2 Time Cost
|
|
|
|
Argon2 performance varies by device. To calibrate the `time_cost` parameter, run the helper function:
|
|
|
|
```bash
|
|
python - <<'PY'
|
|
from seedpass.core.config_manager import ConfigManager
|
|
from utils.key_derivation import calibrate_argon2_time_cost
|
|
|
|
# assuming ``cfg`` is a ConfigManager for your profile
|
|
calibrate_argon2_time_cost(cfg)
|
|
PY
|
|
```
|
|
|
|
The selected `time_cost` is stored in the profile's configuration and used for subsequent key derivations.
